Pilots and flying school operators should ensure they have thorough knowledge of the effects of weather on the pilot’s destinations and plan accordingly prior to flight.
Turning manoeuvres at or close to the aircraft’s critical angle of attack, if mishandled, can lead to a stall that may result in the aircraft entering a spin. Recovery from this condition will take a considerable amount of altitude, dependant on the speed of response by the pilot and the use of appropriate control inputs.
On-site examination of the wreckage and surrounding ground markings indicated that the aircraft impacted terrain at approximately 30° from vertical, in an inverted attitude.
An ATSB investigation report has emphasised the need for operators to heed the advice of aircraft manufacturers with regards to maintenance and upgrades to their fleet.
During the accident sequence, the helicopter’s tail rotor and vertical stabiliser assembly separated from the helicopter.
